Double-acting SRP

WORKING PRINCIPLE

When the up stroke, the plunger goes up, liquid enters the pump cavity 1 through the standing valve, and is compressed in the pump cavity 2, and the liquid is drained into the tubing through the diverter valve; When the down stroke, the plunger goes down, the liquid is compressed in the pump cavity 1, and drained into the tubing through the traveling valve, and the liquid enters into the pump cavity 2 through the ring valve.

FEATURES

1. Small Outer Diameter:Small outer diameter in pumps with same displacement; 2. Large Displacement:Achieve the pumping for oil in up stroke and down stroke; 3. Low Cost:Realiable product performance and high cost performance.

SPECIFICATIONS

Double-acting SRP is a kind of pump that can realize oil production on both up and down stroke. Its system efficiency can be doubled and the displacement is large, which can replace some centrifugal pumps.
